I have serverless_common.yml file for all shared things across all my lambdas and I have serverless.yml in my individual service when I try to import package.patterns in to my individual service yml file I get following error when I do sls print

Serverless Error ----------------------------------------

       at 'package.patterns[0]': should be string

The errors are warning you that you've got two indentation issues. The first is in your serverless_common.yml file. The array items should be indented one place further:

#serverless_common.yml
package:
  patterns:
    - '!target/**'
    - '!tests/**'
    - '!test/**'
    - '!tools/**'
    - '!README.md'
    - '!node_modules/.bin/**'
    - '!serverless/**'
    - '!.*'

The second is in your cron expression. The one-line syntax is only if you're not using other arguments. Since you want to pass enabled: false, you'll need to use the multiline syntax:

#service1/serverless.yml
functions:
  app:
    handler: index.handler
    name: service1
    events:
      - schedule:
          rate: cron(0 09 * * ? *)
          enabled: false

Unfortunately, the syntax you've chosen won't merge the two arrays. You'll have to reference each item in your array individually, or rewrite your serverless.yml into a serverless.js file, which allows you to be more programmatic.

package:
  individually: true
  patterns: 
    - something-specific-to-service1
    - ${file(../serverless_common.yml):package.patterns.foo}
    - ${file(../serverless_common.yml):package.patterns.bar}
    # ... etc
